To all fui/tom if may concern:

Be it known that we, illuminer F. Scrrwnione and li'vrntmar l-l. Fislr., both citizens ol the United States oi rlmerica, andboth re-v siding at Rochester, in the county of Monroe and State of llew Y certain new and useful Improvements in Stamp-ftvxing Machines, of which the 'following is a speciiication.

The invention relates to stamp arising machines, of the general type comprising a portable container adapted to be superposed on an envelope and provided with stamp roll holding` and feeding mechanism, devices for moistening an envelope, and a depressible plunger which serves to feed the stamp strip, operate the envelope moistening mechanism, sever the stamp from the strip, and adir; it to the envelope.

One of the purposes of the invention is to afford a simple, efficient, and durable mechanism for discharging water onto theenvelope, said parts being constructed in such a way as to insure discharging a uniform amount of water onto the envelope', re-

gardless of wear on the controlling parts et the machine.

Vanother purpose of the improvement is to atiord a positive and forceful action inv dischargingthe water from its compartment, and in other ways to insure a proper and adequate supply of water to the envelope.

An additional object ot' the invention is to provide means for retainingl a resilient or rubber pad on the bottom oit the plunger so as to prevent its accidental removal or loosening. Y

Still a further purpose of the invention to ai'ord means for limiting the downward tra-vel of the operating plunger without iinposing any strain on or otherwise atiecting the operating parts of the machine. v

lilith these and other ends Vin view, the invention comprehends the structure that will appear clearlyY 'from the following description, when read in conjunction with the aecompanyimq` drawings, the novel teatures being` pointed out in the claims tollowing the description.

ln the drawings:

orh, have invented mal osition the water commitment beine Figure 3 is a perspective view illustrating Y the means onthe plunger that cooper( tes with the actuator for the water ejecting device;

Figure t is a side elevation or" the machine with )arts broken away, illustrating the position oi the operating plunger at the downward limit of its travel; f

Figure 5 is a bottom plan view of the plunger, and i Figure 6 is a longitudinal vertical sectional view of the same.

Referring more particularly to ythe drawings, in which l like reference numerals throughout the several views indicate the same parts, 1 designates the housing oilr the machine, while 2 is the operating plunger that controls the feeding and cutting of the stamp from the strip, as well known in this class of machine. The housing l is provided with guide slots 3 at the. sides thereof, while l are guide pins carried by the plunger 2 and engaging said slots f3. 4

lt is desirable to prevent the pins et from striking` the bottoms of the slotsf when theplunger is moved downwardly as far as it will go, and to accomplish this, we provide means carried 'by the plunger 2 and engagging the top ci the housing l, so to pref vent the plunger from moving downwardly far enough topermit the pins i to strilre the bottoms ot the slots 8., This Vis pre-terablyV accomplished by. constructing and mounting theA handle 5 on theplunger 2 sov mechanism operates to' discharge water onto he envelope, and the parts having to do with the water containing; and discharging mechanism will now be described.

l nales the water compartment to which water may be supplied when required, through a suitable opening that is normally closed by a threaded plug 11. Pivotally mounted within the. water compartment is a water ejecting device that swings about an axis 12 located at a point betweenA its upper and lower portions. 13 designates a of springs located between the rerwall of the water compartment and the lower portion ot the water ejecting device beneath its pivotal point, and acting to push said lower portion toward the water discharge openings 14C located near the bottoni of the conipartment. The springs 13 are located. in suoli relation as to eiiect a direct Vaction upon the water ejecting device toward the discharge openings, resulting in a positive and powerful operation in discharging the by reason ot' maximum pressure acting di-V rectly toward the water disch rge openings.y

The water ejecting device comprises an integral metallic plate provided with an upturned portionl at its lower end in spaced relation to the body portion ot the plate. The uptuined portion 15 is cut away at 16 to receive the cork member 17 which is retained in said cut-away portion against the body portion ot the water cjecting device and acts to close the discharge openings and prevent passage ot watertherethrough when the parts are in normal position, as shown in Figure 1. It is desirable to prevent the openings 14 from becoming clogged and to vprevent insertion of asharp point into said openings from the exterior, and this is attained by the provision of a series olf pins 18 carried by the water ejecting device and occupying a position within said openings 14 when the parts are in normal position.

The Water ejectiiig device is retracted against the action ofthe springs 13 bythe downward travel ol the plunger 2 through a slidable actuator 2O which is movable horizontally at the top o t' the water compartment 10 and engages'the. upper portion ot the water ejecting device so as to swing the same on its pivotal axis 12. 21 is a member having threaded adjustment on the Vactuatpr and affording an adjustable shoulder which engages and moves the upper portion of the water ejecting device, the adjustment 'of the member 21 making it possible to vary the movement oic the water ejecting device to efi'ect just the proper water discharge.

The actuator 2O carries an operating portion or plate 22 located outside the compartment 10and beveled on its inner surface at opposite portions, as designated at 23. Vllhe plate 22 is preferably constructed ot lvlonel metal, or other similar. allo-y which will withstand wear and has no tendency to rust or corrode if permitted to stand idle after becoming Wet, thus overcoming an objection in prior machines due to the sticking oil parts madeof brass, copper, or other niet-als.

' iiorr- L. Hwhich is preferably cut away at its ed@ receive said frame.

Ais provided with one or more nasi/lie to permit the biturcatcd portions 24k to clear the operating plate 22, the latter is released 'and the spriii TQ 13 throw the water -ejecting gc i device baci; to normal position, at the same time discharging the proper quantity ot water 'through the openings le onto the envelope in preparation for the stamp which is severed and pressed onto the envelope byy the further downv-.fiard travel or" the operating plunger. its the stamp feeding and cutting mea s forms no .part ot this invention, it is unnecessary to show or describe these parts in detail.

@n the return or upward travel ot the pass on the outer side ot the platel 22, so that it the latter has any tendency to stick, the shoe `toi'ces it positively to its normal or innermost position, ready for .another operation when the plunger moves downwardly; Thus the actuator is positively operated by plunger in both directions, through a pulling action on plate 22 tor operating the water electing device, and a pusl'iing operation on said plate, to return said parts to ral position. rfthe bottom ot the plunger 2 is usually provided witheJ pad oi resilient YVmaterial, such as rubber, and in order to retain such pad in place, and prevent its accidental loosening or displacement, we employ a metal rame 30, attached to the plunger in any convenient way, and including flange surroundingthe edge et the resilient p d 31, ll'f 'es to lnorder to retain the body of the resilient pad iii place, the i;

transverse or? tionsx32, which occupy grooves in the i ber pad and hold the central or body portion ot the pad in place, as well 'as its ed.
